Lg cookie 500 photo messages wont send

SOURCE: Not able to make outgoing calls

I cannot make outgoing calls with my iphone. It will show Calls Ended, Calls Failed. Any idea what is the problem with my iphone?

SOURCE: sending pics through text messaging???

The iPhone doesn't support MMS messaging which includes videos, pictures and sound, it only supports text messages. You can email the photos to someone or yourself to get the pictures off your phone on the go.

Here is a thread explaining the problem and the workaround if you are interested.

SOURCE: "error sending message" in my sms text message

This seems to be a recurring problem that I have discovered was a problem with both the original iPhone as well as the iPhone 3g. I just had this happen to me 3 days into owning the phone and the "solution" set forth to me by the apple tech at AT&T was to go into settings and place the phone on airplane mode for a couple minutes and switch it back. This surprisingly worked for me albeit for a matter of minutes. I was then instructed to do a Network reset also through settings under the "Reset" category at the bottom. Although it didn't immediately resolve the problem, after I manually entered my friend's number each time I texted for about 4 texts I have been able to text uninterrupted so far. Not sure this is a permanent fix yet but it's worth a shot for you guys as well.
